Why it works: Parsley and carrot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Brown Rabbit Soup
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Brown the rabbit
Dip the rabbit pieces in flour and fry in butter until browned.
Place the browned rabbit in a soup kettle.
Add the fried onions and pour in 3 quarts of boiling water.
Simmer
Add salt and skim frequently until the soup is clear.
Add parsley, carrots, and whole peppercorns.
Boil gently for about 6 hours.
Adjust seasoning if necessary.
Strain and serve
Strain the soup and let it cool, then skim off the fat.
Reheat the soup before serving and add croutons.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Provides the meat and body of the soup as it simmers for hours.
- Flour
- Coats the rabbit so it browns well and slightly thickens the soup.
- Butter
- Carries the heat for frying and adds browning and richness to the rabbit.
- Onions
- Fried brown first, they add deep color and savory sweetness to the broth.
- Carrots
- Add sweetness and body to the broth during the long simmer.
The step that matters
Skim frequently while the soup simmers. Fat and coagulated proteins rise to the surface during simmering and cloud the broth if left in. Skimming them keeps the soup clear and clean-tasting.
Swap the onion
How well each one fits the dish's main ingredients (rabbit, flour, butter, parsley, carrot):
- Shallotfits better

- Turnipfits better
- Onionthe original
Fit is the average pairing score against rabbit, flour, butter, parsley, carrot. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
